  • Build a docker container with Apache

    To create a docker container with Apache, create a Dockerfile

    mkdir my-app
cd my-app
vi Dockerfile

    Paste following content into the Dockerfile

    from ubuntu:20.04

ARG DEBIAN_FRONTEND=noninteractive

RUN apt-get update && apt-get install -y apache2

RUN echo 'Hello World!' > /var/www/html/index.html

RUN echo '. /etc/apache2/envvars' > /root/run_apache.sh && \
 echo 'mkdir -p /var/run/apache2' >> /root/run_apache.sh && \
 echo 'mkdir -p /var/lock/apache2' >> /root/run_apache.sh && \ 
 echo '/usr/sbin/apache2 -D FOREGROUND' >> /root/run_apache.sh && \ 
 chmod 755 /root/run_apache.sh

EXPOSE 80

CMD /root/run_apache.sh

    Now build an image with command

    docker build -t sevrerok/okapache:1.0 .

    Once image is build, you can see it using docker images command

    [root@instance-20210426-0136 my-app]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

sevrerok/okapache   1.0                 7e0aa2d69a15        2 days ago          72.7MB
[root@instance-20210426-0136 my-app]#

    To start a container with the image, run

    docker container run -d -p 80:80 sevrerok/okapache:1.0

    Build a docker container with Apache

    docker build command is used to create a docker image from Dockerfile.

    To create an image, first lets create a working directory and change to the directory.

    mkdir ~/my-docker-image
cd ~/my-docker-image

    Create a file with name Dockerfile

    vi Dockerfile

    Put following content in it

    FROM ubuntu:18.04

RUN apt update && apt upgrade -y

CMD ["/bin/bash"]

    Now build the docker image with

    docker build -t my-ubuntu .

    This will create a docker image with name “my-ubuntu”.

    To run this, we need to create a container using this image, this can be done with command

    docker run -ti my-ubuntu

    Here i used -ti as we need to run interactively using terminal, this is because our the command we set to start is “/bin/bash” in the Dockerfile.
